If you like this drama watch "You're beautiful" too, the lead actors are the same. However I recommend watching that one first then this one :). Also there were so many tears flowing out during this drama. Definitely recommend watching as it's awesome love the good chemistry between all of the main actors as a few of them seem to be friends beforehand.
SPOILER BELOW!!
Omg cried so much at the ends by it came to the last 5 minutes and thought they wasn't going to get together again but then the sparks flew and now I'm over joyed!
